The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever the water column separation.

Working pressure: 0.2 – 16 bar.
Combines the features of both an air & vacuum valve and an air release valve.
Triple function:
Air & vacuum component discharges large volumes of air during the filling of the system.
Air & vacuum component admits large volumes of air during drainage and at water column separation.
The air release component releases entrapped air in pressurized systems.
Dynamic design allows for high-velocity air discharge while preventing premature closure.
Innovative rolling seal mechanism.
Available in sizes: 1/2″, 3/4″, 1″, 2″ threaded male connections, NPT or BSPT.
